UAB scientists discover the origin of a mysterious physical force

... and the withdrawal of proteins. Both of these are fundamental in biomedical research, since a substantial part of the process of designing new drugs is based on understanding how substances penetrate cell membranes to enter cells. These drugs are often proteins designed to prevent or strengthen the action of ot...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

... proteins activate self-reactive antibodies. "The fundamental problem in all of HIV vaccine research has been that when you inject the envelope of the HIV virus into people or animals, no broadly neutralizing antibodies ?those antibodies that kill most HIV strains ?are made.
